The high demand for wildlife medicines and products creates extremely high pressures on wild populations of a great range of species. Nearly all of the animals having the highest value are species protected under Vietnamese law. However, law enforcement is inherently weak and poaching and trading of protected animals is more often treated as a trivial offense rather than a serious criminal act. Primates are a part of that illegal trade. For several species, the impact on wild populations is tremendous, and several populations have declined dramatically over the last few decades.
